A jar has 19 marbles and 5 of them are green. You pull 3 marbles without replacement. What is the probability that all are green? Write your answer as a fraction. You do not need to simplify
The probability of pulling a green marble on the first draw is 5/19.
Since we are not replacing the marbles, the probability of pulling a green marble on the second draw is now 4/18.
Similarly, the probability of pulling a green marble on the third draw is 3/17.
Therefore, the overall probability of pulling 3 green marbles in a row is:
(5/19) * (4/18) * (3/17) = 60/581
